The rootcause is we can't extend RVVM4SImode into RVVM8DImode on zve32f.
Add a blocker of it to disable such auto-vectorization in this situation.
gcc/ChangeLog:
* config/riscv/autovec.md: Add blocker.
* config/riscv/riscv-protos.h (gather_scatter_valid_offset_p): New function.
* config/riscv/riscv-v.cc (gather_scatter_valid_offset_p): Ditto.
gcc/testsuite/ChangeLog:
* g++.target/riscv/rvv/autovec/bug-2.C: New test.
